State and federal officials gathered Monday to celebrate completion of the project, although the connection between the northbound Grand Parkway and westbound I-10 won’t open until June 30, according to the Texas Department of Transportation. The other connections opened as they were completed, starting in December when work also finished on the Grand Parkway between I-10 and U.S. 290.

North of I-10 is only open to toll-paying customers. Development around the interchange is booming, as businesses expand or relocate.
